Two Boys, Different Interests, One Room?

Q: Help! My two sons are sharing a bedroom and at present it's boring and sparse. We've finally thinned out their overwhelming toy collection and now need to look towards decorating but I'm not feeling very inspired right now! Nairn is 3 and Findlay is 8, they have such a large age gap that mutual interests are sparse....

Our plight is somewhat worsened by living in the UK and not having access to many of the fabulous retailers and stockists that Ohdeedoh recommend.
